select all checkboxes in Python-CGI Web application with javascript
Question
I am working on Python-CGI Web application. I have one table with 3 columns, in which 3rd column has checkboxes. I am trying to use javascript for select all checkboxes functionality to select all the checkboxes of 3rd column.
This is my script:
#!/usr/bin/python
import cgi, cgitb
cgitb.enable()
print "Content-type:text/html\n"
print "\n\n"
print "<html>"
print "<body>"
bigtempl = '''<html>
<head>
</head>
<body>
<center>
<script language="JavaScript">
function selectAll(source) {
checkboxes = document.getElementsByName('colors[]');
for(var i in checkboxes)
checkboxes[i].checked = source.checked;
}
</script>
<table border="0" cellspacing="15">
<tr>
<th> Number </th>
<th> Letter </th>
<th> Select All <input type="checkbox" id="selectall" onClick="selectAll(this)" /> </th>
</tr>
{rows}
</table>
</center>
</body>
</html>'''
rowtempl = """
<tr>
<td> {number} </td>
<td> {letter} </td>
<td> <input type="checkbox" name="colors[]" value={check} /> </td>
</tr>
"""
numbers = [0, 1, 2, 3]
letters = ["A", "B", "C", "D"]
checks = [11, 22, 33, 44]
lst = zip(numbers, letters, checks)
rows = [rowtempl.format(number=number, letter=letter, check=check) for number, letter, check in lst]
rows = "".join(rows)
wholepage = bigtempl.format(rows=rows)
print wholepage
print "</body>"
print "</html>"
Reference taken from here .
This is the output of the script without the code <script>...</script>
But it gets confused with {} of <script> tag. I am getting this error:
A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.
/root/cgi-bin/prblm.py in ()
50 rows = "".join(rows)
51
=> 52 wholepage = bigtempl.format(rows=rows)
53
54 print wholepage
wholepage undefined, bigtempl = '<html>\n<head>\n</head>\n<body> \n <center>\n ... </table>\n </center>\n </body>\n</html>', bigtempl.format = <built-in method format of str object>, rows = '\n<tr>\n <td> 0 </td>\n <td> A </td>\n <td>...heckbox" name="colors[]" value=44 /> </td>\n</tr>\n'
<type 'exceptions.KeyError'>: '\n\t\tcheckboxes = document'
args = ('\n\t\tcheckboxes = document',)
message = '\n\t\tcheckboxes = document'
Can someone help me in resolving this issue? Is there any way I can use javascript with Python and CGI ?

Thanks to this answer ! It resolved the issue.
I added {} outside the function and worked fine!
<script language="JavaScript">
function selectAll(source) {{
checkboxes = document.getElementsByName('colors[]');
for(var i in checkboxes)
checkboxes[i].checked = source.checked;
}}
</script>
